The cultural diffusion of Somali commercial enterprise can be detected in its exotic cuisine, which contains Southeast Asian influences. Due to the Somali people's passionate love for and facility with poetry, Somalia has often been referred to as a "Nation of Poets" and a "Nation of Bards", as, for example, by the Canadian novelist Margaret Laurence.[2] Somalis have a story-telling tradition.

Somali art is the artistic culture of the Somali people, both historic and contemporary. These include artistic traditions in pottery, music, architecture, wood carving and other genres. Somali art is characterized by its aniconism, partly as a result of the vestigial influence of the pre-Islamic mythology of the Somalis coupled with their ubiquitous Muslim beliefs.

The Somali language is the official language of Somalia. It is a member of the Cushitic branch of the Afro-Asiatic language family, and its nearest relatives are the Afar and Oromo languages. Somali is the best documented of the Cushitic languages,[3] with academic studies of it dating from before 1900.

Somali dialects are divided into three main groups: Northern, Benaadir and Maay. Northern Somali (or Northern-Central Somali) forms the basis for Standard Somali. Benaadir (also known as Coastal Somali) is spoken on the Benadir coast from Adale to south of Merca, including Mogadishu, as well as in the immediate hinterland. The coastal dialects have additional phonemes which do not exist in Standard Somali. Maay is principally spoken by the Digil and Mirifle (Rahanweyn) clans in the southern areas of Somalia.

Since Somali had long lost its ancient script,[4] a number of writing systems have been used over the years for transcribing the language. Of these, the Somali alphabet is the most widely used, and has been the official writing script in Somalia since the government of former President of Somalia Siad Barre formally introduced it in October 1972.[5]

In addition to Somali, Arabic is an official national language of Somalia.[7] Many Somalis speak it due to centuries-old ties with the Arab World, the far-reaching influence of the Arabic media, and religious education.

English is also widely used and taught. Italian used to be a major language, but its influence significantly diminished following independence. It is now most frequently heard among older generations. Other minority languages include Bravanese, a variant of the BantuSwahili language that is spoken along the coast by the Bravanese people.

With few exceptions, Somalis are entirely Muslims,[8] the majority belonging to the Sunni branch of Islam and the Shafi`i school of Islamic jurisprudence, although some are also adherents of the Shia Muslim denomination.[9]Sufism, the mystical dimension of Islam, is also well-established, with many local jama'a (zawiya) or congregations of the various tariiqa or Sufi orders.[10] The constitution of Somalia likewise defines Islam as the religion of the Somali Republic, and Islamic Sharia as the basic source for national legislation.[11]

Islam entered the region very early on, as a group of persecuted Muslims had, at Prophet Muhummad's urging, sought refuge across the Red Sea in the Horn of Africa. Islam may thus have been introduced into Somalia well before the faith even took root in its place of origin.[12]

Although Somalian women were initially excluded from the many male-dominated religious orders, the all-female institution Abay Siti was formed in the late 19th century, incorporating Somali tradition and Islam.

In addition, the Somali community has produced numerous important Islamic figures over the centuries, many of whom have significantly shaped the course of Muslim learning and practice in the Horn of Africa, the Arabian Peninsula, and well beyond. Among these Islamic scholars is the 14th century Somali theologian and juristUthman bin Ali Zayla'i of Zeila, who wrote the single most authoritative text on the Hanafi school of Islam, consisting of four volumes known as the Tabayin al-Haqa’iq li Sharh Kanz al-Daqa’iq.

Christianity is a minority religion in Somalia, with over 1,000 practitioners.

The clan groupings of the Somali people are important social units, and clan membership plays a central part in Somali culture and politics. Clans are patrilineal and are divided into sub-clans and sub-sub-clans, resulting in extended families.[13]

Somali society is traditionally ethnically endogamous. So to extend ties of alliance, marriage is often to another ethnic Somali from a different clan. Thus, for example, a recent study observed that in 89 marriages contracted by men of the Dhulbahante clan, 55 (62%) were with women of Dhulbahante sub-clans other than those of their husbands; 30 (33.7%) were with women of surrounding clans of other clan families (Isaaq, 28; Hawiye, 3); and 3 (4.3%) were with women of other clans of the Darod clan family (Majeerteen 2, Ogaden 1).[14]

When not dressed in Westernized clothing such as jeans and t-shirts, Somali men typically wear the macawis (ma'awiis), which is a sarong-like garment worn around the waist and a large cloth wrapped around the upper part of their body. On their heads, they often wrap a colorful turban or wear the koofiyad, an embroidered taqiyah.

During regular, day-to-day activities, women usually wear the guntiino, a long stretch of cloth tied over the shoulder and draped around the waist. The guntiino is traditionally made out of plain white fabric sometimes featuring with decorative borders, although nowadays alindi, a textile common in the Horn region and some parts of North Africa, is more frequently used. The garment can be worn in many different styles and with different fabrics. For more formal settings such as weddings or religious celebrations like Eid, women wear the dirac, a long, light, diaphanous voile dress made of cotton, polyester or saree fabric. The dirac is related to the short-sleeved Arabian kaftan dress. It is worn over a full-length half-slip and a brassiere. Known as the gorgorad, the underskirt is made out of silk and serves as a key part of the overall outfit. The dirac is usually sparkly and very colorful, the most popular styles being those with guilded borders or threads. The fabric is typically acquired from Somali clothing stores in tandem with the gorgorad. In the past, dirac fabric was also frequently purchased from South Asian merchandisers.

Married women tend to sport head-scarves referred to as shash, and also often cover their upper body with a shawl known as garbasaar. Unmarried or young women, however, do not always cover their heads. Traditional Arabian garb such as the jilbab is also commonly worn.

Additionally, Somali women have a long tradition of wearing gold and silver jewelry, particularly bangles. During weddings, the bride is frequently adorned in gold. Many Somali women by tradition also wear gold necklaces and anklets. Additionally, xirsi, an Islamic necklace likewise donned in Ethiopia and Yemen, is frequently worn.

Somali art is the artistic culture of the Somali people, both historic and contemporary. These include artistic traditions in pottery, music, architecture, wood carving and other genres. Somali art is characterized by its aniconism, partly as a result of the vestigial influence of the pre-Islamic mythology of the Somalis coupled with their ubiquitous Muslim beliefs. However, there have been instances in the past of artistic depictions representing living creatures such as the golden birds on the Mogadishan canopies, the camels and horses on the ancient rock paintings in northern Somalia, and the plant decorations on religious tombs in southern Somalia, but these are considered rare. Instead, intricate patterns and geometric designs, bold colors and monumental architecture were the norm.

Additionally, henna is an important part of Somali culture. It is worn by Somali women on their hands, arms, feet and neck during weddings, Eid, Ramadan, and other festive occasions. Somali henna designs are similar to those in the Arabian peninsula, often featuring flower motifs and triangular shapes. The palm is also frequently decorated with a dot of henna and the fingertips are dipped in the dye. Henna parties are usually held before the wedding ceremony takes place.

Somali scholars have for centuries produced many notable examples of Islamic literature ranging from poetry to Hadith. With the adoption of the Latin alphabet in 1972 to transcribe the Somali language, numerous contemporary Somali authors have also released novels, some of which have gone on to receive worldwide acclaim. Of these modern writers, Nuruddin Farah is probably the most celebrated. Books such as From a Crooked Rib and Links are considered important literary achievements, works which have earned Farah, among other accolades, the 1998 Neustadt International Prize for Literature. Farah Mohamed Jama Awl is another prominent Somali writer who is perhaps best known for his Dervish era novel, Ignorance is the enemy of love. Mohamed Ibrahim Warsame is considered by many to be the greatest living Somali poet, and several of his works have been translated internationally.
